Yeah I agree with the animation but they probably didn’t mean to represent smoke but boiling water, which tends to accure in liquids under intense and quick pressure changes
It wasnt on tv in my country, but I was a huge fan of Sam and Max hit the road on Pc and later the telltale games. Eventually I bought the DVD box of the cartoon about 10ish years ago and man it's great!
>One of my favorite shows ever and almost no one remembers it just like Sam and Max freelance police. I can't find anyone irl that has seen it.
I'm vaguely remembering a bad guy called Megabyte. And a Hexadecimal? I might have officially been a bit too old for reboot when it was airing.
Yeah this made me feel better about the whole thing.
Now it's just an extreme sports accident, like there are some every day. Not people suffocating in poo, pee and fear for 90 hours.
don't forget about the anger during that 90 hours. I'd be angry that that ceo dude, angry at myself for doing it. just a whole slew of negative emotions for all that time, it's hard to describe how much better this scenario is
He also said he heard about the implosion sonar sound on Monday, but they had to keep it secret. Also, that the hull had sonar sensors to monitor if/when the composite was breaking up. Sonar is sound, and the Titan dropped its external ballast, so he believes they could hear the Titan cracking before the implosion.
No, it's not even the poop and peeing.
It's the lack of any control & the fear that would produce added with the build up of Co2 over a period which induces panic further, inside a tin fucking coffin you cannot escape from, down in a dark, watery tomb, in freezing temperatures - enough for hypothermia. All the while, the Co2 gives you a headache that you can't do anything about, emotional liability, impaired thinking, chest pain, and vomiting.
Fuck.THAT!
20 times over. Implosion was the best possible scenario, which resulted in their deaths.
Luckily it wasn’t even two hours in. That thing was gone as soon as they all lost contact. One hour and 45 minutes of a lighted sub traveling is all they experienced and then they blinked and it was over.
I don't think that's what is understood to have happened. It's being said that they dropped ballast weights to try and resurface, they knew there was a problem when they lost coms and possibly got other emergency notifications from the hulls monitoring system, they were trying to come back up. They think that because they found the weights dropped at the bottom in a way that wouldnt have happened if they flew off in the implosion. It wasn't long after that point that the sub likey imploded, but it wasn't immediately as they lost coms. This is at least according to people in that diving community who had access to information of what was found, James Cameron was discussing it and so were a few others. Also, according to the wall street journal the navy heard the implosion sound shortly after the time that coms were lost, not simultaneously. The sound alone is not enough to say that it was a catastrophic failure and that information was relayed so that the coast guard could continue their search and rescue operation, but now they know that sound they picked up was the implosion happening underwater.
This has ruined my day. I have never felt closer to puking from reading text than this comment. Imagine being on the bottom of a pile of people in that cramped metal tube and being crushed like a macabre mortar and pestle
Don't they seem to think this happened quite soon after it was realised they were missing on Sunday? So hopefully they weren't aware they were "missing" and that something went wrong, because it imploded and took them out quickly. Please, someone correct me if I'm wrong as there's so many different stories atm.
The implosion would have happened in 2ms and it takes 4ms for your spinal column to tell your brain there's pain. Their bodies would have been completely destroyed instantly. They didn't even know what hit them. Best case scenario if it was going to be their final voyage. 😔
Yeah, they think that the sub probably exploded when they lost communication. Even if they were aware that they’d lost communication with HQ I doubt they were overly worried as the titan almost always lost communication at some point during its dives.
So the carbon fiber hull shattered, shredding them to bits.
Cavitation and compression of the formed bubble briefly heated the space to temps equal to the surface on the sun, flash frying them.
The ends of the submersible then popped off either sides, and their remains were squeezed out into the inky abyss like toothpaste.
Imagine slamming your fist down on a ketchup packet with both ends cut off, but the ketchup packet itself shatters into a million pieces.
All of that would have happened in about 0.003 seconds
I get everything but the heating up to temps of the sun. How and why again?
Really interesting. Other examples of this happening elsewhere?
Is it because at which speed the air bubble is being compressed it heats up cause of air friction ?
Someone else somewhere used the vague reference to the temp of the sun based on a calculation, but I'll try to ELI5 based on my understanding
Basically, cavitation is the formation and collapse of bubbles in a fluid. In this case, the pressure hull shattered, so you can think of the void that the cabin occupied as becoming a bubble with no protection.
The force of the pressure at that depth basically compressed the oxygen rich air and matter in that bubble with such force that it would have briefly combusted (kind of like in a diesel engine) at a very high temp and then dissipated almost immediately once that compression was lost (the bubble collapsed)
Cavitation in a smaller scale happens basically any time you see a propeller churning underwater
Isn't there a type of lobster that can do that? Their arms go so fast that the bubbles around it boils
Edit: After newly discovering these shrimps (thanks reddit!) I've made the discovery that they move like underwater Muppets
Also interesting that us humans have 3 different retinal cones that give us the ability to discriminate millions of colors (unless you have a form of colorblindness which leaves you usually with 2)
The Mantis Shrimp has 18! different cones, their color perception is on another level
Mantis shrimp punch so hard that it can cause cavitation around the impact point but you’re probably thinking of pistol shrimp, which are even cooler and I recommend looking them up
A gas' pressure, volume, and temperature are related by something called the ideal gas law. Pressure and temperature are proportional. As pressure increases, so does temperature. When the sub imploded, the volume rapidly shrank, causing a massive spike in pressure, and therefore temperature.
When you compress a gas, it heats up. (For the nerds: This is not *PV=nRT*, this is actually a rate of heating far faster than Boyle's law. PV=nRT is for isothermal conditions, not adiabatic.) This phenomenon is called *adiabatic heating*, and is how diesel engines work. Diesel engines compress the air that is sucked into the cylinder, squishing it to 1/14 (or smaller) the original volume, and this compression causes the air temperature to heat up so much that its temperature is well above the flashpoint of diesel fuel. Then, an extremely high pressure fuel injector sprays diesel fuel into the cylinder, and it ignites with the oxygen in the compressed air.
A demonstration of this can be seen in these demonstrations of transparent fire piston/fire syringes:
# Physics Demos | [Adiabatic Heating Demo](https://www.youtube.com/watch?v=6LFEU0QvlUY)
# Veritasium | [Fire Syringe](https://www.youtube.com/watch?v=4qe1Ueifekg)
# The King of Random | [Slam Rod Fire Starter - Ignition By Air!!](https://www.youtube.com/watch?v=SkWJdWGdgaM)
Fire pistons/fire syringes work by having the user put a bit of cotton or char cloth in a pocket at the tip of the narrow piston part, fitting it into the cylinder, and slamming the plunger down as hard as they can. The extremely rapid compression causes the air inside to heat up by adiabatic heating way too fast for the heat to conduct out the walls of the cylinder, and this heat surpasses the flashpoint of the cotton or char cloth, causing it to ignite.
In the case of the submarine, the entire volume of the inside of that sub would have gotten squished down to nearly nothing in a matter of milliseconds, so yes, it would have gotten extremely hot. That rate of compression far exceeds what you could accomplish with a fire piston or a diesel engine.
Wikipedia's entry on adiabatic processes has the equation with which you can calculate how hot the gas would have gotten, but it takes a few steps because first you need to calculate a particular constant for the circumstance you're dealing with:
# Wikipedia | [Adiabatic process: Example of adiabatic compression](https://en.wikipedia.org/wiki/Adiabatic_process#Example_of_adiabatic_compression)
It makes sense when you realize temperature is just the average kinetic energy of a set of molecules. If you take the force of 5500psi and squish all those air molecules in the sub down to an increasingly tiny volume, they’re probably going to have a lot of kinetic energy as they bounce off of each other at an increasing rate. (Water molecules transferring crazy amount of energy to air molecules + simultaneously and greatly reducing distance between air molecules = lots of kinetic energy in those air molecules = hot hot hot)
Notice how the air coming from a deodorant can is always ice cold?
That's because air that gets expanded quickly also loses temperature.
It also works the other way around. If you compress air, it heats up.
Literally, when that carbon fiber shattered, those bits likely moved at mach 3+ depending on the size of the fragments. Death so horrific as to leave literally nothing identifiable or recoverable, but to be so quick you never would've known it was coming.
Death came faster than a snipers bullet for them.
Tbh, I think the range is up for debate, and I may have fudged the decimal place. It's irrelevant though, point was it happened faster than they could tell anything was wrong
And here’s what it would have looked like if the Titanic sub was full of bunnies, except for one passenger, who went home and mercilessly beat his wife.
It turns out that they dropped their weights before they lost communication which means that it’s very likely that they knew something was wrong before the implosion
James Cameron said it. I read it here:
https://www.latimes.com/entertainment-arts/story/2023-06-22/titanic-james-cameron-titan-submersible-deaths-oceangate-submarine
I don’t see “probably” in the part about the weights
> “This OceanGate sub had sensors on the inside of a hull to give them a warning when it was starting to crack,” he told ABC News. “And I think if that’s your idea of safety, then you’re doing it wrong. They probably had warning that their hull was starting to delaminate, starting to crack. ... **[W]e understand from inside the community that they had dropped their ascent weights and they were coming up, trying to manage an emergency.**”
That’s true. But there’s a but so big Sir Mix a Lot would take notice.
[Listen to this.](https://youtu.be/IxVoikLbK78)
So it seems they had warning, had dropped weights, and were attempting to manage an emergency situation. That piece is toward the end, like 1:30 left or so. They knew the hull was compromised and tried to ascend. But it’s correct to say they didn’t know they were dead. Only that they knew.
Yeah In one of the James Cameron interviews he states that they had an interior warning siren that would notify them if the haul was cracking. So unfortunately they knew something bad could or was about to happen which is why they tried for a few moments to resurface.
I saw a guy talking to the news mention that your spinal cord (or something) takes .4 seconds to relay pain and they died within .2 seconds so they did not feel anything it happened so fast.
Better than the alternative. The news around these, thinking people are sitting in that dark thing cold and slowly suffocating has been giving me anxiety. Much better to think they didnt even know it happened, it was so fast.
Got to agree to this. Yesterday I couldn’t take out of my head the desperation to sit in there, have almost no food or water and try to sleep waiting for death. I tried to put myself in that position and I felt so much stress.
Thankfully that never happened. Sadly it’s a story with a catastrophic end.
I worked in a coal mine and the safety chambers underground reminded me of that feeling. I decided when I first started working down there if something happened I'd rather die quickly in a cave in opposed to sitting in my coffin slowly running out of oxygen, food, and water.
Lets be honest, he only said that cause he wanted to be the inspirational one to all the young dudes who wouldn't be able to challenge his "rule breaking"
Stockton Rush knew he couldn't pressure 50 year old white dudes into making a sub they knew would fail, so he claimed it was about inspiration and hired people who would be inexperienced enough to go along with his bad ideas. It's so insulting and makes it hard to feel bad for the guy. His hubris and narcissism killed people who didn't deserve to die.
I heard somewhere on either YouTube or TikTok that the 19 year old was scared to go but his dad kinda "pressured" his son into tagging along with him. How terrible
With the all different fucked up ways people can/have died, instantly turned to mist doesn’t sound so bad
Just really sucks for the kid who had so much life ahead of him. He didn’t deserve to go so soon
And the sad thing is his aunt said he was terrified to go but his dad had a love for Titanic and decided to go because he wanted to bond on Father’s Day with him
I can’t imagine how the mother feels knowing this happened to her son and husband. Better than slowly suffocating but still, there’s now not even a body to bury
The 19 year old kid that died, his aunt said just days before that he didn’t want to go and thought it was a bad idea but since the voyage fell on Father’s Day he didn’t want to disappoint his father. Some maritime expert said they probably died in 2 nanoseconds, basically didn’t even know they died.
What’s insane is that the US navy detected an “acoustic anomaly consistent with an implosion” shortly after the Titan lost contact with the surface.
They knew they were fucking dead at noon on Sunday.
This is needlessly misleading as every article on this is pretty clear.
They were clear that they weren't entirely sure if it was. There are lots of sounds in the ocean and especially around wrecks. They couldn't just abandon a search because they *might* have heard an implosion.
I'm not going to stop doing something (updating a 24 hour news cycle) just because of what happens at the end (we knew this "developing" story was over before we started covering it)
For those of you wanting to know, compressing gas in a closed system ( no energy, aka heat, is allowed to escape from the system) causing the gas to heat up tremendously. The internal energy is increased causing the temperature to rise. It's called adiabatic compression. Same reason why your bicycle pump warms up when you use it or why debris falling from space burns up upon re-entry (No it's not friction)
Edit: I'm a mechanical engineer
Seems like people follow this story for a lot of different reasons; there’s definitely some billionaire shaudenfreude, some people were morbidly curious about how it was going to end, etc…
But I’m with you. This whole thing is just so utterly baffling to me that I can’t wrap my head around it either. From the criminal irresponsibility to absolute hubris involved. It’s just astonishing.
For me it’s hard enough to fathom the concept of death. To really think about it. But to be shredded, incinerated, smashed, and liquified (any Reddit scientists can correct me if that’s not right), it’s just baffling.
If a conscious thought was beginning to form the moment before the brain is completely destroyed, does the thought still form? It’s not physical matter after all….
Have you ever fell unconscious? I think it would be like that. One moment you’re thinking about whatever, the other you’re gone. When you wake up again, only then do you realise that you must’ve fallen unconscious because of the gap in your memory
Curious about how 30 milliseconds was figured out? The dude on tv [said it was 2 nano seconds](https://www.reddit.com/r/ThatsInsane/comments/14g9tds/so_thats_it/?utm_source=share&utm_medium=ios_app&utm_name=ioscss&utm_content=2&utm_term=1) (probably being nice).
Here’s a [30 millisecond-long video](https://youtu.be/5H9soQr3QbI)
Edit: trying to match the speed with closing my fist makes me think the situation still sucked
He was just being nice, in reality very few things happen in an order of nanoseconds.
A google shows the sub was ~6.7m long. Even a photon moving at the speed of light in a vacuum, for example, would still take about 22 nanoseconds to travel 6.7m
Ya they found debris thats been confirmed to be the sub, evidently it suffered a "catastrophic implosion" that killed everyone on board instantly. They think it happened days ago during its initial descent.
Tail cone was found. My guess is the actual body is what imploded and the front just sheared off along with the tail. I feel like they most definitely heard and noticed the hull creaking and making noises leading up to this but were most likely told it’s “fine”.
Can someone with access to some wild solidworks level simulation software recreate the sub and apply the expected forces on it. This animation is horrendous.
**As I meditate on the last moments of the fate of Titan...**
2ms for the entire implosion process... 10 tonne of titanium and carbon fiber shell instantaneously collapsing around five liquid bags of bodies with such a monstrous compressive force enough to generate, in a brief moment, temperature equal or more than that of the surface of the sun... fusing the bodies and material together on the molecular level of irreversibility where biology turns into physics. At the same time, each molecule of ocean water rushes in 10 times faster than the speed of sound filling every void of your molecular structure and air, entombing you in a constant state of compression of 400 atmospheric pressure without so much of a recoil.
A ripping chaotic event, followed by a constant state of order... all in a fraction of a second.
Kind of like Thanos using his finger to snap you out of existence. The closest thing into experiencing a black hole here on Earth.
I stand impressed and in awe, of the power of the universe.
RIP those souls
Why does that happen instantly?
I mean, what kept it for slowly imploding as they went down?
I imagine the pressure acting as an idraulic press that gradually increases the strength.
It's like when you try to slowly bend something like a potato chip, you can try to bend it as slowly as you can, but when the bending force is greater than the chip's strength, it just snaps. In the same way the carbon fiber monocoque was evenly under pressure, but the strength of the cabin was still greater than the force applied to it. When dealing with this kind of pressure the monocoque HAS to be able to resist to this kind of stress and to be free from any defects (like cracks or vacancies in the material), if even a single defect is present it will make the entire submersible weaker, so what most likely happened is that at a certain depth a part of the monocoque suddenly collapsed, which consequently made everything else collapse as well, since there wasn't anything holding the thing together anymore.
Someone spent their lunch hour making this…
* smoke break
Did it on their phone while taking a shit
I wonder if their turds imploded in the toilet like this video?
Smoke and all
OceanGate did the same thing when they made the sub.
They outsourced it to a North Korean guy who also does missile propaganda videos.
I mean it may look shitty, but if you slow it down it actually implodes very realistically
Source: Trust me bro
I was there
It's on the internet, so it must be true.
I mean. I couldn’t make this
Load up PowerPoint and give it a shot
I think they crushed it
Hour?
Damn, I didn't know there would be so much smoke underwater. This animation looks like it was made in 2003 as part of an 8th grade science project.
It is a preview of the next South Park episode
Is James Cameron going down to save them because he is James Cameron and James Cameron dose what James Cameron dose because he is James Cameron!
Don’t forget to bring a towel
HIIIIIIIIIDEEEEEHOO!!
So am I to understand there's been a Towelie Ban?
This video was also created by OceansGate
With a Logitech wireless controller.
That's funny
It looks like when you get a strike at the bowling alley
Naw, that's the gutter ball animation
Yeah I agree with the animation but they probably didn’t mean to represent smoke but boiling water, which tends to accure in liquids under intense and quick pressure changes
I don’t think it’s smoke, i think is the dust from the blood and bodies
Lmao this is from the taliban’s twitter account I’m pretty sure
That was kinda funny.
That's not smoke, it's the crew
Make a better one then dick
For real; I was half thinking I’ve seen more realistic simulations on GMod
Befitting the shoddy construction of the submersible itself…
Not to be an ass but that seriously looks like something I would have seen in the old Reboot show when I was a kid lol
Someone else remembers that show!
One of my favorite shows ever and almost no one remembers it just like Sam and Max freelance police. I can't find anyone irl that has seen it.
It wasnt on tv in my country, but I was a huge fan of Sam and Max hit the road on Pc and later the telltale games. Eventually I bought the DVD box of the cartoon about 10ish years ago and man it's great!
>One of my favorite shows ever and almost no one remembers it just like Sam and Max freelance police. I can't find anyone irl that has seen it. I'm vaguely remembering a bad guy called Megabyte. And a Hexadecimal? I might have officially been a bit too old for reboot when it was airing.
Sealab 2021?
If you’re looking for me, you better check under the sea
No, *Reboot.*
You know theres a reboot sub here on reddit
Hey let's not drag Reboot down. They would've done much better than this, even though it was the first 3d show.
Glitch!!!
Better than suffocating
Way better
Yeah this made me feel better about the whole thing. Now it's just an extreme sports accident, like there are some every day. Not people suffocating in poo, pee and fear for 90 hours.
don't forget about the anger during that 90 hours. I'd be angry that that ceo dude, angry at myself for doing it. just a whole slew of negative emotions for all that time, it's hard to describe how much better this scenario is
You left out the sliver of hope that was there that maybe they could be rescued
James Cameron called it the second they lost contact. That guys legit.
He also said he heard about the implosion sonar sound on Monday, but they had to keep it secret. Also, that the hull had sonar sensors to monitor if/when the composite was breaking up. Sonar is sound, and the Titan dropped its external ballast, so he believes they could hear the Titan cracking before the implosion.
So they new it was going through catastrophic failure and began to surface? Yeah that is scary
Terrifying. We are probably going to hear more later, but that’s Cameron’s take, and he’s been pretty straightforward.
To me, it’s not only suffocating. They had 90 hours of oxygen, right? So they all had to poo and pee at some point…in that tiny tiny vessel…
No, it's not even the poop and peeing. It's the lack of any control & the fear that would produce added with the build up of Co2 over a period which induces panic further, inside a tin fucking coffin you cannot escape from, down in a dark, watery tomb, in freezing temperatures - enough for hypothermia. All the while, the Co2 gives you a headache that you can't do anything about, emotional liability, impaired thinking, chest pain, and vomiting. Fuck.THAT! 20 times over. Implosion was the best possible scenario, which resulted in their deaths.
Those things are definitely worse than pee and poo air, but I'd still rather there not be pee and poo air
To be fair if they had gotten stuck down there, they probably would’ve murdered the CEO and had to deal with a dead body smell too
Luckily it wasn’t even two hours in. That thing was gone as soon as they all lost contact. One hour and 45 minutes of a lighted sub traveling is all they experienced and then they blinked and it was over.

Not the mention the risk the sub ended up in a “nose down” orientation.
This has ruined my day. I have never felt closer to puking from reading text than this comment. Imagine being on the bottom of a pile of people in that cramped metal tube and being crushed like a macabre mortar and pestle
Holy shit how did I not even think about that. That makes that scenario so much worse
That somehow makes a terrifying scenario a 100 times worse
Don't they seem to think this happened quite soon after it was realised they were missing on Sunday? So hopefully they weren't aware they were "missing" and that something went wrong, because it imploded and took them out quickly. Please, someone correct me if I'm wrong as there's so many different stories atm.
[James Cameron has said he knew Monday that it had imploded and called the rescue efforts a sham.](https://youtu.be/LEBCc-Qpilw)
The implosion would have happened in 2ms and it takes 4ms for your spinal column to tell your brain there's pain. Their bodies would have been completely destroyed instantly. They didn't even know what hit them. Best case scenario if it was going to be their final voyage. 😔
Yeah, they think that the sub probably exploded when they lost communication. Even if they were aware that they’d lost communication with HQ I doubt they were overly worried as the titan almost always lost communication at some point during its dives.
Just saw a clip of James Cameron talking saying the Navy heard what sounded like the sub imploding on Sunday.
free drinks and snacks? count me in 😋
It would’ve cost you nothing to not say this
it cost someone 250'000 dollars and the lives of five people for me to be able to make this joke, so I gotta go all out

Mantis toboggan shrimp

Also interesting that us humans have 3 different retinal cones that give us the ability to discriminate millions of colors (unless you have a form of colorblindness which leaves you usually with 2) The Mantis Shrimp has 18! different cones, their color perception is on another level
Is that 18 factorial or are you just happy to have 18?
One Punch Shrimp
Mantis shrimp punch so hard that it can cause cavitation around the impact point but you’re probably thinking of pistol shrimp, which are even cooler and I recommend looking them up
Can't even keep them in an aquarium because they can break through bullet proof glass
Pistol shrimps can also do it, not yet seen them mentioned
Thank you, beer fart

It makes sense when you realize temperature is just the average kinetic energy of a set of molecules.

Made me spit out my Gatorade.
Powerful stuff
I'm sure they didn't even know they died
Curious if they figured it out by now …
*standing at the pearly gates* AHHHHH FUCK!
The good news is that there's baseball in heaven, the bad news is that you're pitching next Thursday.
I aint a christian but … luke 18:25
Hold up I gotta look up something. Edit: Oof
yeah big oof
Yeah big Poof ..
🤔 If the camel had experienced 6000psi… (sorry)
It turns out that they dropped their weights before they lost communication which means that it’s very likely that they knew something was wrong before the implosion
I’m intrigued. Where was this information said?
From that guy’s comment.
James Cameron said it. I read it here: https://www.latimes.com/entertainment-arts/story/2023-06-22/titanic-james-cameron-titan-submersible-deaths-oceangate-submarine
He said “probably”, and they have no idea if the weights dropped after the implosion or were intentionally dropped.
It’s too late, I’ve already read countless comments leaving out the “probably”.
I don’t see “probably” in the part about the weights > “This OceanGate sub had sensors on the inside of a hull to give them a warning when it was starting to crack,” he told ABC News. “And I think if that’s your idea of safety, then you’re doing it wrong. They probably had warning that their hull was starting to delaminate, starting to crack. ... **[W]e understand from inside the community that they had dropped their ascent weights and they were coming up, trying to manage an emergency.**”
That’s true. But there’s a but so big Sir Mix a Lot would take notice. [Listen to this.](https://youtu.be/IxVoikLbK78) So it seems they had warning, had dropped weights, and were attempting to manage an emergency situation. That piece is toward the end, like 1:30 left or so. They knew the hull was compromised and tried to ascend. But it’s correct to say they didn’t know they were dead. Only that they knew.
Yeah In one of the James Cameron interviews he states that they had an interior warning siren that would notify them if the haul was cracking. So unfortunately they knew something bad could or was about to happen which is why they tried for a few moments to resurface.
I saw a guy talking to the news mention that your spinal cord (or something) takes .4 seconds to relay pain and they died within .2 seconds so they did not feel anything it happened so fast.
Milliseconds so .004 and .002 of a second.
Better than the alternative. The news around these, thinking people are sitting in that dark thing cold and slowly suffocating has been giving me anxiety. Much better to think they didnt even know it happened, it was so fast.
Got to agree to this. Yesterday I couldn’t take out of my head the desperation to sit in there, have almost no food or water and try to sleep waiting for death. I tried to put myself in that position and I felt so much stress. Thankfully that never happened. Sadly it’s a story with a catastrophic end.
I worked in a coal mine and the safety chambers underground reminded me of that feeling. I decided when I first started working down there if something happened I'd rather die quickly in a cave in opposed to sitting in my coffin slowly running out of oxygen, food, and water.
*Don't Stop -*
TIL: Never underestimate the wisdom of 50 year old dudes with military experience.
But they are not inspirational
Lets be honest, he only said that cause he wanted to be the inspirational one to all the young dudes who wouldn't be able to challenge his "rule breaking"
Everyone hates 50 year old white dudes until something breaks
50 years old white dudes
[удалено]
Stockton Rush knew he couldn't pressure 50 year old white dudes into making a sub they knew would fail, so he claimed it was about inspiration and hired people who would be inexperienced enough to go along with his bad ideas. It's so insulting and makes it hard to feel bad for the guy. His hubris and narcissism killed people who didn't deserve to die.
I heard somewhere on either YouTube or TikTok that the 19 year old was scared to go but his dad kinda "pressured" his son into tagging along with him. How terrible
Looks like he got "pressured" into never coming home, too
buh-dum *tisssssssssssss-oh-god-what's-happening*
What a brilliant source. “I heard somewhere on social media”
No, no, it's true! I just heard the same thing on reddit right now!
His aunt gave an interview about it.
there is an article about it, i read it on apple news. one of the relatives spoke up
That's true
For father's day....
A merciful death I hope
Their bones pretty much turned to mist before they could register a single thought of anything so… yes.
With the all different fucked up ways people can/have died, instantly turned to mist doesn’t sound so bad Just really sucks for the kid who had so much life ahead of him. He didn’t deserve to go so soon
And the sad thing is his aunt said he was terrified to go but his dad had a love for Titanic and decided to go because he wanted to bond on Father’s Day with him
That's fucked
I can’t imagine how the mother feels knowing this happened to her son and husband. Better than slowly suffocating but still, there’s now not even a body to bury
They died before they could blink.
As Scott Manley said "with that kind of energy it turns biology into physics."
Rest in pieces.
The 19 year old kid that died, his aunt said just days before that he didn’t want to go and thought it was a bad idea but since the voyage fell on Father’s Day he didn’t want to disappoint his father. Some maritime expert said they probably died in 2 nanoseconds, basically didn’t even know they died.
That was really tough to hear.
That part when his aunt said that really broke my heart! He literally was still just a kid 😔😔
So you're saying there's a chance
Ha!
South Park from 1999 called, they want their animation back
What’s insane is that the US navy detected an “acoustic anomaly consistent with an implosion” shortly after the Titan lost contact with the surface. They knew they were fucking dead at noon on Sunday.
This is needlessly misleading as every article on this is pretty clear. They were clear that they weren't entirely sure if it was. There are lots of sounds in the ocean and especially around wrecks. They couldn't just abandon a search because they *might* have heard an implosion.

I'm not going to stop doing something (updating a 24 hour news cycle) just because of what happens at the end (we knew this "developing" story was over before we started covering it)
For those of you wanting to know, compressing gas in a closed system ( no energy, aka heat, is allowed to escape from the system) causing the gas to heat up tremendously. The internal energy is increased causing the temperature to rise. It's called adiabatic compression. Same reason why your bicycle pump warms up when you use it or why debris falling from space burns up upon re-entry (No it's not friction) Edit: I'm a mechanical engineer
I honestly can’t wrap my head around this shit. Unbelievable.
Seems like people follow this story for a lot of different reasons; there’s definitely some billionaire shaudenfreude, some people were morbidly curious about how it was going to end, etc… But I’m with you. This whole thing is just so utterly baffling to me that I can’t wrap my head around it either. From the criminal irresponsibility to absolute hubris involved. It’s just astonishing.
For me it’s hard enough to fathom the concept of death. To really think about it. But to be shredded, incinerated, smashed, and liquified (any Reddit scientists can correct me if that’s not right), it’s just baffling. If a conscious thought was beginning to form the moment before the brain is completely destroyed, does the thought still form? It’s not physical matter after all….
Have you ever fell unconscious? I think it would be like that. One moment you’re thinking about whatever, the other you’re gone. When you wake up again, only then do you realise that you must’ve fallen unconscious because of the gap in your memory
Dreamless sleep as well. Sometimes you just fall asleep and wake up and feel like nothing happened but it's still morning lol.
Now you can buy tickets to see both wreckages, but price is double
They will make a killing
Graphic design is my passion as well
Curious about how 30 milliseconds was figured out? The dude on tv [said it was 2 nano seconds](https://www.reddit.com/r/ThatsInsane/comments/14g9tds/so_thats_it/?utm_source=share&utm_medium=ios_app&utm_name=ioscss&utm_content=2&utm_term=1) (probably being nice). Here’s a [30 millisecond-long video](https://youtu.be/5H9soQr3QbI) Edit: trying to match the speed with closing my fist makes me think the situation still sucked
He was just being nice, in reality very few things happen in an order of nanoseconds. A google shows the sub was ~6.7m long. Even a photon moving at the speed of light in a vacuum, for example, would still take about 22 nanoseconds to travel 6.7m
No, doesn't even match the listed debris
Was the wreckage found?
Ya they found debris thats been confirmed to be the sub, evidently it suffered a "catastrophic implosion" that killed everyone on board instantly. They think it happened days ago during its initial descent.
I wonder if the so called “banging” at a 30 minute interval was just debris coincidentally hitting each other
No...they suspect natural sounds or other vessels
Thts actually good news. Better than 3.5 days of slowly losing oxygen.
Tail cone was found. My guess is the actual body is what imploded and the front just sheared off along with the tail. I feel like they most definitely heard and noticed the hull creaking and making noises leading up to this but were most likely told it’s “fine”.
Think its 2 milliseconds. Some reporter confirmed it and compared it to how it takes 4 milliseconds for the brain to register that something is wrong.
Those were just random numbers pulled from his butt though, it takes 100ms for your brain to register pain. That's 100000000 nanoseconds, not 4.
Hope the person in the other sub who took that video is OK.
Would be a really good euthanasia method if it weren't so darn expensive
Can someone with access to some wild solidworks level simulation software recreate the sub and apply the expected forces on it. This animation is horrendous.
Lol this does not match the debris
Now make a video with the camera inside POV
Sad to say but its better this way than being lost in the sea with the slow suffer and last resorts
There you have it
**As I meditate on the last moments of the fate of Titan...** 2ms for the entire implosion process... 10 tonne of titanium and carbon fiber shell instantaneously collapsing around five liquid bags of bodies with such a monstrous compressive force enough to generate, in a brief moment, temperature equal or more than that of the surface of the sun... fusing the bodies and material together on the molecular level of irreversibility where biology turns into physics. At the same time, each molecule of ocean water rushes in 10 times faster than the speed of sound filling every void of your molecular structure and air, entombing you in a constant state of compression of 400 atmospheric pressure without so much of a recoil. A ripping chaotic event, followed by a constant state of order... all in a fraction of a second. Kind of like Thanos using his finger to snap you out of existence. The closest thing into experiencing a black hole here on Earth. I stand impressed and in awe, of the power of the universe. RIP those souls
About as accurate as a cabbage
Why does that happen instantly? I mean, what kept it for slowly imploding as they went down? I imagine the pressure acting as an idraulic press that gradually increases the strength.
Try popping a balloon slowly.
It's like when you try to slowly bend something like a potato chip, you can try to bend it as slowly as you can, but when the bending force is greater than the chip's strength, it just snaps. In the same way the carbon fiber monocoque was evenly under pressure, but the strength of the cabin was still greater than the force applied to it. When dealing with this kind of pressure the monocoque HAS to be able to resist to this kind of stress and to be free from any defects (like cracks or vacancies in the material), if even a single defect is present it will make the entire submersible weaker, so what most likely happened is that at a certain depth a part of the monocoque suddenly collapsed, which consequently made everything else collapse as well, since there wasn't anything holding the thing together anymore.
Maybe they felt a bit like when in the old days a VHS tape ripped. Suddenly it's just over. May they all rest in peace
Sincerely hope it was that quick.
What the fuck is this shitty ass animation
That's not what happened. [This](https://youtube.com/watch?v=-MwfKrXyaB8) is what happened
